Should I Charge My Battery At 2 Or 6 Amps. Multiply the capacity of the battery by the charging C rating to find the amps to set it at. Charge until current drops below.
A battery with a rating of 1000 mAh should be able to provide 1 amp of current for 1 hour. These should be considered the maximum. An average car battery has a capacity of around 48 amp hours which means that fully charged it delivers 1 amp for 48 hours 2 amps for 24 hours 8 amps for 6 hours and so on.
If discharged half way I want a 2 amp charge for 3 to 4 hours.
My battery is not dead just seems weak. In fact at the 10 amps output the battery is able to gain enough juice pretty quickly sometimes in just an hour. Even if you leave your battery for charging at a 2 amp charger it may lead to overcharging if the charger is not turned off after the battery is. 54 amp X 75 or 75 6 amp 675 hours.
